Emma Roberts and Evan Peters had an "unfortunate misunderstanding" which led to the 22-year-old actress' arrest in Montreal. Police were called to the Montreal hotel, in which the couple were staying, after receiving reports of a dometic violence.

According to TMZ, attention was drawn to the couple after a fellow hotel guest complained about noise issuing from the couple's room.

Although Roberts was arrested for domestic violence it is believed she was not the sole perpetrator and Peters did retaliate.
